Triangle-Angles

function triangleAngles(a, b, c){
  let A = Math.acos((b^2 + c^2 - a^2)/2*b*c)
  let B = Math.acos((a^2 + c^2 - b^2)/2*a*c)
  let C = Math.acos((b^2 + a^2 - c^2)/2*a*b)
  return [Math.floor(A * 57.2958),
          Math.floor(B * 57.2958),
          Math.floor(C * 57.2958)]
}

Hi guys. This function returns [null, null, null]. Does anyone have an idea why?
